Optimization of olive-oil extraction using nonlinear H-infinity control

Nonlinear H-infinity Control: an Lmi Approach

In this paper, we consider the problem of robust H-infinity Control for a class of uncertain nonlinear systems. We derive LMI conditions for analyzing regional robust stability and performance based on Lyapunov functions which are polynomial functions of the state and uncertain parameters. More specifically, we provide an energy bound on the input disturbance which guarantees that the state of ...

Active Suspension vibration control using Linear H-Infinity and optimal control

In this paper, the 1/4 vehicle model have been simulated. The vehicle body acceleration using optimal control has been optimized. The vehicle ride comfort is achieved by using robust control, and it has been compared with optimal control. The active suspension can help the vehicle to have a good dynamic behavioral. In this paper, two degrees of freedom dynamic vibration model of a general ve...

optimization of olive oil extraction to enhance efficiency and quality

olive oil is one of the oldest known vegetable oils, ranking sixth in world production. since it is extractedfrom fresh fruit and used without aging, the conditions of oil production are very important. during theextraction of virgin olive oil, the milling and malaxation steps are vital for increasing oil yield and quality.in this study, the effect of milling (single or double), temperature of ...

Tracking of Rigid Body Motion via Nonlinear H-infinity Control

In the present paper the problem of tracking of rigid body motion in SE(3) in the presence of torque disturbances is addressed. A penalty variable whose Euclidean norm is a measure of the tracking error is deened. Then nonlinear H 1 control theory is applied to design a control law such that the closed loop system has L 2-gain from the torque disturbances to this penalty variable for a xed posi...
